Abstract

LiNb3Cl8 crystallizes in the orthorhombic Cmce space group. The structure is three-dimensional. Li1+ is bonded to five Cl1- atoms to form distorted LiCl5 trigonal bipyramids that share corners with four NbCl5 square pyramids, edges with two NbCl5 square pyramids, and an edgeedge with one LiCl5 trigonal bipyramid. There are a spread of Li–Cl bond distances ranging from 2.35–2.82 Å. There are three inequivalent Nb+2.33+ sites. In the first Nb+2.33+ site, Nb+2.33+ is bonded to five Cl1- atoms to form NbCl5 square pyramids that share corners with five NbCl5 square pyramids, a cornercorner with one LiCl5 trigonal bipyramid, and an edgeedge with one LiCl5 trigonal bipyramid. There are a spread of Nb–Cl bond distances ranging from 2.46–2.81 Å. In the second Nb+2.33+ site, Nb+2.33+ is bonded to five Cl1- atoms to form NbCl5 square pyramids that share corners with four NbCl5 square pyramids and corners with two equivalent LiCl5 trigonal bipyramids. There are a spread of Nb–Cl bond distances ranging from 2.46–2.68 Å. In the third Nb+2.33+ site, Nb+2.33+ is bonded to five Cl1- atoms to form NbCl5 square pyramids that share corners with five NbCl5 square pyramids, a cornercorner with one LiCl5 trigonal bipyramid, and an edgeedge with one LiCl5 trigonal bipyramid. There are a spread of Nb–Cl bond distances ranging from 2.46–2.79 Å. There are six inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a 2-coordinate geometry to two Nb+2.33+ atoms. In the second Cl1- site, Cl1- is bonded in a 3-coordinate geometry to two equivalent Li1+ and one Nb+2.33+ atom. In the third Cl1- site, Cl1- is bonded in a 3-coordinate geometry to one Li1+ and two Nb+2.33+ atoms. In the fourth Cl1- site, Cl1- is bonded in a distorted T-shaped geometry to one Li1+ and two Nb+2.33+ atoms. In the fifth Cl1- site, Cl1- is bonded in a 2-coordinate geometry to two Nb+2.33+ atoms. In the sixth Cl1- site, Cl1- is bonded in a distorted T-shaped geometry to one Li1+ and two Nb+2.33+ atoms.

Cyclic moisture reactivation of calcium sorbents for long duration thermochemical energy storage

The transition to a flexible and reliable energy infrastructure, using electro-thermal energy generation technologies such as geothermal, concentrated solar power, and nuclear, usually demands simultaneous advancement of thermal energy storage (TES) to support on-demand electricity generation and industrial applications while mitigating the inherent intermittency of renewable energy sources and power outages from direct energy generation. Among TES technologies, thermochemical energy storage (TCES) based on calcium looping emerges as a compelling high-power energy storage candidate due to its high reaction enthalpy, compatibility with elevated operating temperatures, and abundance of low-cost materials. However, the long-term durability of calcium-based sorbents for TCES is hindered by surface sintering and particle aggregation, leading to performance degradation over repeated thermal cycles. This study explores a moisture hydration-based strategy to regenerate a degraded calcium sorbent and mitigate performance degradation for long duration TCES. The addition of moisture transforms calcium oxide into calcium hydroxide and produces intercalation water layers, associated with a regenerated surface area and reduced calcium oxide crystallite size. Both these effects are beneficial in restoring the sorbents' reactivity for carbonization. Additionally, an optimized hydration-assisted reactivation protocol balances the recovered energy storage capacity with heating penalty required for moisture removal from hydrated samples, resulting in an enhanced energy storage capacity up to 176% compared to benchmark sorbents that undergo cycling without reactivation after 60 cycles. In conclusion, these results highlight the potential of hydration-assisted reactivation to enhance the long-term performance of TCES, providing an effective pathway to advancing electro-thermal storage technologies.
